In Star Wars there is a planet.

This planet's name is Iridonia and is home to a species known as the Zabrak,examples of Zabrak are Darth maul from Star Wars episode 1 and Bao Dur from kotor 2.

In kotor1, we meet an armored humanoid mercenary whose race is "Iridonian".

This must mean he is from Iridonia or is a Zabrak, correct?

WRONG

Iridonian is referred to as a different species, a warrior people who were bloodthirsty and violent.

Yet, in Kotor2, Bao Dur, a Zabrak engineer from Iridonia, is referred to as an Iridonian, despite being Zabrak.

WHAT GIVES? Just what IS an Iridonian? What is their relation to Iridonia and the Zabrak? Why is Bao Dur called an Iridonian?

Later, in 2008, the Knights of the Old Republic Campaign Guide was released by Wizards of the Coast. It lists a gear template for "Iridonian Manufacture," which describes Iridonians as "a mysterious species known for their savagery and aggressiveness." The gear template gives Iridonian weapons and armor extra resistance to bludgeoning attacks and a bonus to certain attacks that emphasize brute strength.[3] This description matches that of the Manaan Iridorian, but not the pre-existing species known alternatively as both Iridonians and Zabraks, who are said to be a more peaceful species. This change, from "Iridorian" to "Iridonian," was confirmed to be deliberate by Rodney Thompson, one of authors of the Campaign Guide, who explained that Lucasfilm Ltd. stipulated the change and that it was "the KOTOR video game that was in error.

Fixed.

Oh okay then, so the blood thirst species is Iridorian? While zabrak that grew up on Iridonia are Iridonian? Got it.
